Conor McGregor becomes the newest endorser of one of the leading sports apparel company, Reebok. With the new sponsorship deal, McGregor becomes the first Ultimate Fighting Championship, or UFC, athlete to come from Europe.

Reebok Brand President Matt O'Toole said in a press release that Conor truly embodies their brand, adding that the Irishman's hard work, determinate, and confidence have brought him to where he is today. The statement said that McGregor's role as Reebok's new ambassador will be featured in the new collection of footwear and apparel, which will be distributed for more than 35 million people who train like fighters around the globe.

"I believe my potential in the ring is limitless, but it all comes down to the training you put in pre-fight," McGregor said. "With a top fitness brand like Reebok behind me, there's no telling what I can do in the Octagon."

Reebook also took to Twitter to announce its new partnership with McGregor. Shortly after Reebok made its announcement, McGregor even congratulated the sports apparel brand for "netting the biggest signature in the game."

McGregor, also known as "The Notorious," had an outstanding UFC debut in 2013. Coming off from an eight-fight winning streak at Cage Warriors Fighting Championship, McGregor has successfully won all four of his fights in the UFC, three of which via technical knockout.

On Jan. 18, McGregor will headline UFC Fight Night 59 against Siver at Boston's TD Garden, where he is anticipated to wear his first-ever "Reebok Walkout T-Shirt." If he beats Siver on Sunday's bout, he may be one win away from getting his shot at the featherweight title.

MMA Junkie reported that McGregor could earn a potential title fight with UFC champion Jose Aldo if all goes in favour of him on Sunday. As such, UFC President Dana White believes that a featherweight showdown between Aldo and McGregor could be the biggest fight of the year and could even beat the Jones vs. Cormier fight, according to White. The fight could reportedly take place in Las Vegas, Brazil, and McGregor's native Ireland but in the meantime, McGregor has his eyes focused on Sunday's bout and leave the ring as a winner.
